Download the instant AP image from support.arubanetworks.comStart a TFTP server on your PCMake sure that the TFTP server root is where your image file isBoot the AP with a serial cable attachedCTRL + C to break to the prompt if necessary

Now use this command to upgrade the AP image.

upgrade os :

E.g.upgrade os 192.168.0.1:ArubaInstant_Orion_5.0.3.0-1.1.0.0_29082

Type reset to reboot the AP. You should now see Image is signed; verifying checksum... passed instead of Image is signed; verifying checksum... failed! 0x36da16c3

NOTE: Only do this if you see Image is signed; verifying checksum... failed! 0x36da16c3 also there may be other ways to fix this that I'm not aware of!
